ARM: l2x0: only write to debug registers on PL310 PL310 errata #588369 and #727915 requires writes to the debug registers of the cache controller to workaround known problems. Writing these registers on L220 may cause deadlock, so ensure that we only perform this operation when we identify a PL310 at probe time. Signed-off-by: Will Deacon <will.deacon@arm.com>
